        If this hardware is bad (its just a shit desktop I'm using for this purpose) I'm making the boss purchase equipment.

        Oh, this isn't a server? Very good chance that this is a hardware failure causing the corruption.

          Can be a URE as well. Without RAID, URE comes up and this is often what it would look like.

              MD RAID 10 is configured on this box for the storage space. So I can check that as well.

                Should be the very first thing to check.

                    That is common in scenarios where you have filesystem corruption.

                          it looks like xvda is having issues according the current screen.

                          Might have to replace that drive...

                            At the moment the system appears to just be progressing through the blk_update_request with I/O errors for individual sectors on XVDA.

                            Should I abort this operation and find a replacement drive? Is it worth it to let this continue?

                              Hard to say. Real data on it? Would try to get a last backup first before doing filesystem operations.

                                Yeah, all comes down to the value of recovery, really.

                                  I don't mind tearing down the system, it's only running 1 VM that I'm backing up my VM's too. Which those delta's get pushed off nightly to another disk.

                                        Manual fsck is no fun.

                                          At least all of the instructions are there, and this is a learning experience.
